As shown in FIG. 23 , Patent Document 1 heat-seals the peripheral edge e of a film having a heat-sealable synthetic resin on the inner layer, and attaches a dispensing member b to one side of the packaging bag. A packaging bag a for enteral enteral nutrient, a so-called pouch for liquid food, equipped with an injection member c having a lid member is disclosed. Holes (hanging means) d for suspending the pouch for liquid food are respectively formed in the upper e1 and the lower e2 of the peripheral edge e, and the holes d2 formed in the lower peripheral edge e2 are poured out. When cutting and opening the spout of the member b and attaching the pipe for supplying the contents, it is for hanging on a hanging tool (not shown). At the time of administration, the hole d1 or d3 formed in the upper peripheral edge e1 is hooked on the hanging tool.

Patent Document 2 also relates to a nutrient packaging bag having the same purpose as Patent Document 1, and its feature is that it can be suspended by a flexible sheet piece as shown in FIG. A filling device c for injecting the filling material is provided at one edge of the main body of the liquid food pouch a, and an extraction device b for pouring the filling material is provided at the other edge, and the filling device The inlet c is formed larger than the outlet b of the extraction tool. Further, in this liquid food pouch, one side edge is folded inward as a gusset f to form a bottomed liquid food pouch, and the other side edge is heat sealed without forming a gusset. Yes. As a result, when the liquid food pouch is transported, the gusset forming portion can be placed as the bottom, and stable transportation can be performed.

As shown in FIG. 25 , Patent Document 3 is configured such that the lower part of the liquid food pouch a serves as a content pouring outlet, and tears the vicinity of the tip using the cut portion g <b> 2. b.
In addition, when water is replenished after the contents are poured out, a part of the package is cut using the cut portion g1 above the liquid food pouch, and the subsequent pouch is sealed using a zipper-type open / close seal. Part h is performed.

The liquid food pouches disclosed in Patent Documents 1 and 2 are each a separate injection port (filler) larger than the spout as a means for replenishing water after administration of the pouch contents. It is a requirement to bother to install.
Further, Patent Document 3 has a simple method of tearing a part of a pouch to form an opening without using a separate filling tool as a hydration means, and a zipper-type sealing is used as a sealing structure for that part. Using fasteners.

However, as in Patent Documents 1 and 2, incorporating not only the spout for dispensing but also a spout of another member for replenishing moisture etc. into a part of the pouch not only makes the manufacturing process complicated. As a one-way liquid food pouch, it is expensive and uneconomical. In addition, it may not be possible to dispose of the pouch after it has been used. There is a problem that extra time is required for the work.

Further, as in Patent Document 3, a means for tearing a part of the pouch and opening the pouch is simple and excellent in economic efficiency. In some cases, the contents of the liquid food pouch are always in contact with each other, so that the liquid contents may reach the unsealed portion beyond the zipper fitting portion before unsealing. In that case, when opening a zipper at the time of opening, a liquid splashes or a finger contacts a liquid and it is unsanitary. Moreover, when resealing a pouch using this sealing tool, there is a risk that foreign matter may adhere to the sealing tool part or various bacteria may enter, which is not preferable from the viewpoint of hygiene. .

In view of the current state of the prior art, the object of the present invention is to use an extra effort to seal the opening after opening without using a separate spout and using a sealing tool. In addition, by using a specific sealing tool to form the opening and seal the opening, it is possible to prevent foreign substances and germs from entering as much as possible and to easily replenish and re-seal drinking water etc. It is to provide a bag-like container with a spout such as a liquid food pouch.
Another object of the present invention is to avoid a crotch tearing state where the hanging portion and the planned opening portion are bent in different directions even when the hanging portion and the planned opening portion are separately formed through the cut portion.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an explanatory view showing an embodiment of a bag-like container 1 with a spout according to the present invention, and FIGS. 2 to 7 are explanatory views showing other embodiments of the bag-like container with a spout. FIG. 8 is an enlarged view of a cross-sectional structure of a plastic linear fastener in a liquid food container, which is a preferred application of a bag-like container with a spout, and FIG. 9 is a plan view thereof. FIG. 10 is a schematic view showing a cross-sectional view of a configuration in which a film having a linear fastener and a weakened portion is formed of different members, and FIG. 11 shows different fusion states between the linear fastener and the container inner surface. It is a schematic diagram shown by sectional drawing of b).

  The bag-like container 1 with a spout of the present invention (hereinafter sometimes simply referred to as a “container”) is roughly sealed, and usually seals the peripheral portion 13 of the body made of a polygonal plastic film constituting the front and back. In addition, a content pouring tool 11 having a spout 10 is attached to a part of the peripheral edge portion, and a plastic linear fastener is disposed on the inner side in the vicinity of the peripheral edge portion of the container spaced apart from the content pouring tool 11. 2 is fused, and a scheduled opening portion 15 is provided between the linear fastener 2 and the seal portion 13. The unscheduled opening portion 15 is a portion that is opened using a cutting tool such as scissors or a knife after the linear fastener 2 is used, and the portion can be opened with fingers without using a cutting tool. May be formed as a weakened portion provided with a score or the like, or a notch or the like may be made in the opening start portion. In addition, although the seal | sticker of a container peripheral part has preferable heat sealing, you may carry out by ultrasonic sealing.

Although the shape of the bag-like container with a spout of the present invention is not particularly limited, it is usually based on a quadrangle as described in the above-mentioned patent documents and FIGS. 1 to 7 of the present specification . It is often formed into an irregular polygon shape. In addition, the corner | angular part of polygonal shape does not need to have a corner | angular part exactly | strictly, The shape which tied the straight line and the straight line with the curve may be sufficient. Any polygonal shape may be used as a whole. The plastic film constituting the body of the bag-like container 1 with a spout is preferably transparent so that the administration state of the contents can be confirmed from the outside. A composite film of more than one layer is used.

Since this plastic film seals the periphery, when this is done by heat sealing, the inner layer must be made of heat-sealable plastic, even in the case of a composite film. Yes, usually heat seal layer (inner layer) / barrier layer (intermediate layer) / surface layer (outer layer), heat seal layer (inner layer) / base material layer (intermediate layer) / barrier layer (intermediate layer) / surface layer ( It is preferable to use a laminated film comprising an outer layer). Among them, a laminated film comprising polyethylene terephthalate in which an inner layer is polypropylene, an intermediate layer is nylon, and an outer layer is a thin film such as aluminum oxide or inorganic silicon as a barrier layer on the inner layer side. It is preferable to use it because it is excellent in gas barrier properties, puncture resistance and transparency.
In this case, the intermediate layer has a function as a barrier layer for preventing deterioration or decay of the contents. In addition to nylon and a vapor deposition layer, an ethylene-vinyl alcohol copolymer resin film (EVOH), etc. Is used. In addition to polypropylene, polyethylene or the like is used as the inner layer, and nylon or the like is used as the outer layer in addition to polyethylene terephthalate.

  The contents pouring tool 11 in the bag-like container 1 with a pouring port of the present invention is also referred to as a spout molded from a generally hard plastic having resistance to retort such as polypropylene resin, and also described in each of the above-mentioned patent documents. Any known dispensing tool can be used. Since this pouring tool is attached in a state of being fused between the inner layers of the plastic film at the periphery of the plastic film constituting the body of the liquid food container, the material of the pouring tool is the film constituting the container. It must be able to be fused with the inner layer, but the shape of its tip may be tapered so that it can be easily inserted into the contents discharge pipe, A device may be appropriately arbitrarily devised such as forming an uneven shape on the outer periphery of the part. In addition, the spout of the bag-like container with a spout of the present invention is formed by attaching a separate content extraction tool equipped with a spout nozzle to the container body, and performing a spout operation such as the installation of a meridian tube. However, the container body may be formed in a nozzle shape without using the contents pouring tool as a separate member, and may be configured as a spout.

As shown in FIGS. 8 and 9 , the plastic linear fastener 2 according to the present invention is attached to two opposing film-like base materials 22 and 22 and has a linear protrusion in the longitudinal direction on one surface. The linear fastener itself is used for resealing the food packaging bag after opening, with a portion 21b formed and a concave portion 21a that engages with the convex portion formed on the surface facing the portion 21b. It is known as “Ziplock” (registered trademark). In the present invention, it is important that the convex portion 21 b and the concave portion 21 a of the linear fastener 2 are liquid-tightly blocked from the container internal space 24 where the content outlet 10 is located by the film having the weakened portion 23. is there. And the film which has the said weakened part may be comprised with film 22 'of a different member from this linear fastener 2, as shown in FIG. It is preferable that the number of members is small. In that case, the container inner side (opposite side of the planned opening portion side) of the two film-like base materials 22 to which the convex portion 21b and the concave portion 21a of the linear fastener 2 are attached is extended and the weakened portion 23 is interposed. It is important that the film-like base materials 22 are connected to each other.

  In this configuration, the portion of the linear fastener film-like base material 22 that extends toward the inside of the container is connected via the weakening portion 23, so that the container contents are convex of the film-like base material 22. The container contents do not contact the convex portion and the concave portion of the linear fastener 2, that is, the engaging portion itself, only by contacting the surface opposite to the surface on which the portion and the concave portion are formed. Therefore, the contents of the container do not adhere to the engaging portion of the linear fastener 2 and its periphery. For example, in the liquid food container, the opening scheduled portion 15 outside the linear fastener is opened after administration, and the linear fastener 2 is opened. Even if a part comes into contact with the outside air, it is possible to prevent foreign matter and germs from entering due to the contents adhering to the part, and it is possible to prevent water from the opened linear fastener part in a clean state. The function as the replenishment part 15a which implements etc. can be fulfilled.

  The weakened part of the linear fastener does not break when the contents are contained in the container, and it is sufficient that the weakened part of the linear fastener is maintained in an articulated state to the extent that it is subsequently broken after opening the linear fastener. It can be easily formed by means such as thinning or forming a score. The linear fastener needs to have thermal adhesiveness to the inner surface of the container and retort resistance at the time of sterilization of the contents, and is formed by extrusion molding using a polypropylene resin or the like. In that case, the weakening part can be comprised by extruding thinly from the other part of a film-like base material, for example. Moreover, it is good also as a multilayered structure of two or more layers using different resin in the uneven | corrugated formation surface side of a fastener, and the sealing surface side for the purpose of improving thermal adhesiveness.

The linear fastener 2 is fused to the container body by fusing the film base material 22 of the linear fastener and the body film on the inner surface of the container with heat or ultrasonic waves. In order to partition the container internal space so that the contents and the engaging portion of the fastener do not come into contact with each other, both ends of the linear fastener need to be sealed. Preferably, both end portions are connected and sealed to a seal portion at the peripheral edge of the container. An example of the form of fusion between the container body and the film-like substrate is schematically shown in FIGS . Further, as shown in FIG. 11 (a), the fusion along the linear convex portion and the concave portion is performed by setting the film length between the fusion portion closest to the weakened portion and the convex portion and the concave portion. When the length between the a and a ′ and the weakened portion 23 is b and b ′, respectively, and the height when the convex portion and the concave portion are engaged is h,
a + a ′ + h <b + b ′
It is preferable to have the relationship in order to break the weakened portion after the engagement of the linear fastener is released.

As shown in FIG. 11 (a), the fuselage between the container body and the film-like base material is not performed on the weakened portion side of the convex portion and the concave portion, and the convex portion as shown in FIG. 11 (b) . In addition, there is a form in which the film-like base material on both sides of the concave portion is fused to the container body . Preferably, as shown in FIG. The film-like base material on the side opposite to the side having the weakened portion is fused to the container body along the convex portion and the concave portion, and the film-like base material portion on the weakened portion side from the convex portion and the concave portion is the container body material. It is preferable not to fuse with the film because the fusing work is easy.

The container outer end side of the linear fastener may be sealed inside the container peripheral portion so that it can be opened, but the container is also covered with the container body by positioning the outer end of the linear fastener inside the container. It is preferable to seal the outer end normally as with the other peripheral edges. In that case, an opening score or the like may be formed between the linear fastener and the container peripheral seal portion on the outer end side. Further, the position where the contents pouring tool 11 is mounted is not particularly limited, but usually, either the lower peripheral edge of the container as shown in FIG. 11 or any of the containers as shown in FIG. Corners are preferred.

  The content pouring tool 11 and the linear fastener need only be spaced apart from each other, and the formation location is not particularly limited. However, when the container is suspended with the pouring tool 11 down, If the fastener is positioned at a position higher than the height of the position, it is preferable to pour water from the opening. The bag-like container with a spout of the present invention is generally used by being hung on, for example, a hook-shaped suspending tool (not shown), and in this case, at least the contents pouring tool of the container is attached. It is necessary that the suspending means 14 is formed on the side opposite to the side on which it is located.

As the suspending means 14, it is most common to make a hole at a predetermined portion of the peripheral edge (seal part) 13, but it is not a complete hole but may be a notch that allows a suspending tool to enter. . The suspending means 14 is generally provided at the seal portion of the container opposite to the location where the contents pouring tool 11 is attached, but this suspending means is used when the contents of the container with the spout are poured out. For example, in the configuration shown in FIG. 1 , for example, preparation before administration of a liquid food container is performed by forming (not shown) on the side on which the content extraction tool is attached. It can also be used during work such as connecting a pipe to the content extraction tool.

3 to a container having the configuration shown in FIG. 7 shows another embodiment of the invention, the embodiment of FIG. 3, a seal portion hanging means 14 are formed, the encapsulating linear fastener It is considered that the portions that are separated are separated by the cuts 16 so that the opening operation of the linear fastener 2 portion can be performed independently of the suspending means 14. In addition, the contents pouring tool 11 can be covered with a cap 11 ', so that the handling of the pouch can be performed more hygienically.

4 and 5 are formed in a state in which the scheduled opening portion 15 is protruded outward from the seal portion where the suspending means 14 is formed, and the suspending means 14 is formed. Each of the sealing parts is opposed to the contents extraction tool 11 attached to the heat sealing part in a state where the opposed lower corner part is cut obliquely, and the suspended container is well balanced. There is. Moreover, since the content extraction tool 11 does not protrude from the corner of the container because the seal portion to which the content extraction tool 11 is attached is notched obliquely, efficient stacking is possible at the time of packaging. The advantage is that it is not necessary to form an extra space in the packaging box.

The embodiment shown in FIG. 6 is a modification of the embodiment shown in FIG. 3 , and has a wide cut 16, the inner end of the planned opening portion 15 is a convex portion, and this portion is a flap 17. In addition, the center part of the front end of the flap 17 may be made to coincide with the opening-scheduled portion 15, and the part may be formed in, for example, an ε-shape 17a as illustrated. Thereby, there is an advantage that the opening operation of the linear fastener 2 part is more stably performed. Further, since the flap 17a remains without being cut after the planned opening portion 15 is cut off with scissors or the like, by holding the container inlet at the time of water addition and placing a finger on the flap 17a, the held container is hard to slip and easy to grip. .

In the embodiment of FIG. 7, the bag-like container with a spout defined in claim 1 can be used as a standing pouch, and has a side opposite to the side on which the content spout is attached. By setting it as the bottom part 18, the container before use can be mounted in the stable state.

Figure 20 is an enlarged perspective view illustrating a layer structure of a bottom portion of the spout-equipped bag shaped container 1c of the present invention, FIG 21 is a perspective view showing another embodiment of the bottom 22 is 20 FIG.

The bag-like container 1c with a spout according to the present invention roughly seals the peripheral portions 13 of a plurality (usually three) of polygonal plastic films forming the front surface A, the back surface B, and the bottom surface C, The contents pouring tool (pouring port) 11 is attached to a part of the portion, and the characteristic feature thereof is that a gripping portion 29 is formed on the peripheral edge of the pouch spaced from the contents pouring tool 11. The plastic linear fastener 2 is mounted at a position spaced inward of the container from the outer end seal portion 25 in the grip portion so as to cross the grip portion 29 , and the linear fastener The inside of the container lies in that the film-like base material on which the linear fasteners are extended is connected to each other via the weakened portion . The seal is usually a heat seal, but may be an ultrasonic seal.

  The shape of the bag-like container 1c with a spout according to the present invention is appropriately determined in consideration of the convenience of use. From the viewpoint of forming the grip portion 29, it is formed into an irregular polygonal shape based on a quadrangle. Often done. The corners of the polygonal shape do not need to have strictly corners, and may be a shape obtained by connecting a straight line and a straight line with a curved line, and may be approximately a polygonal shape as a whole. . Also in this invention, the plastic film constituting the body of the bag-like container 1c with a spout is preferably transparent so that the administration state of the contents can be confirmed from the outside, or a single film may be used. However, a composite film having two or more layers is usually used.

The shape of the gripping portion 29 is not particularly limited, but the opening portion can be easily opened by grasping the gripping portion 29 with one hand at the time of water addition from the replenishment portion 15a and lightly squeezing it. It is preferable to have a protrusion that can be grasped with a finger or one hand. The tip of the grip 29 has a flap 24 extending at least on one of the side end seals 26 of the grip 29 and a finger hook 27 to secure the grip when water is added. It is preferably formed (see FIGS . 14 and 17 to 19 ). The flap 24 and the finger hook portion 27 are provided to prevent the container from slipping down when the grip portion 29 is grasped and lifted, and are formed on one or both ends of the side end seal portion 26 to The shape is not particularly limited as long as it can be hung.

Between the outer end seal portion 25 of the grip portion 29 and the linear fastener 2, a scheduled opening portion 15 that is a tearing portion at the time of opening is provided. Specifically, the scheduled opening portion 15 may be printed with a dotted line indicating that it is a scheduled opening portion, for example. It is also possible to make notches at the ends to make it easier to start tearing, and if an easy opening mechanism such as a weakening line by score or laser processing is provided, only fingers without using a cutting tool such as scissors It is preferable because it can be cut. In addition, when the flap 24 is extended in the side end seal part 26, it is necessary to provide the flap 24 so that at least a part of the flap 24 is positioned on the linear fastener 2 side from the planned opening line (see FIG. 14 ).

As described above, the weakened portion of the linear fastener 2 used in the present invention is not broken when the contents are contained in the pouch and is configured to be broken continuously after opening the linear fastener . It is as follows.
The bag-like container with a spout of the present invention usually has a bottomed structure in which the peripheral portions of three films composed of a surface film A, a back film B, and a bottom film C are heat sealed.
